The invention relates to a reinforcing support layer (9) of the carcass (2) of a pneumatic vehicle tire (11) having reinforcing supports, wherein the reinforcing supports are arranged substantially parallel to each other and embedded in elastomeric material within the reinforcing support layer (9), wherein at least one reinforcing support is designed as a cord (20) consisting of at least two threads (21, 22), which are twisted together, and wherein the at least two threads (21, 22) are made of polyester. The problem to be solved by the invention is that of providing a reinforcing support layerof the carcass of a pneumatic vehicle tire which has increased durability against impact stress. Said problem is solved in that the at least two threads (21, 22) are twisted together into the cord (20) by means of a twist factor of 250 to 400, preferably 270 to 350, particularly preferably 280 to 320. The invention further relates to a pneumatic vehicle tire (11) having such a carcass layer (9).

    一种车辆充气轮胎(11)的胎体(2)的增强织物层(9),该增强织物层具有增强织物,其中这些增强织物在该增强织物层(9)内大体上相互平行地布置并且嵌入到弹性体材料中,其中至少一个增强织物设计为由至少两条丝线(21,22)制成的帘线(20),这些丝线彼此末端捻绕,并且其中该至少两条丝线(21,22)由聚酯制成。目的在于,提供一种车辆充气轮胎的胎体的增强织物层,该增强织物层在冲击负荷下具有提高的耐久性。这通过以下方式实现:该至少两条丝线(21,22)以250至400、优选270至350、特别优选280至320的捻系数彼此末端捻绕成该帘线(20)。此外,本发明涉及一种具有这种胎体层(9)的车辆充气轮胎(11)。
